1) modified l2_multi.py and added log.debug in _handle_PacketIn() , like the
following:
def _handle_PacketIn (self, event):
log.debug("Installing 11111111111")
def flood ():
""" Floods the packet """
if self.is_holding_down:
log.warning("Not flooding -- holddown active")
msg = of.ofp_packet_out()
# OFPP_FLOOD is optional; some switches may need OFPP_ALL
msg.actions.append(of.ofp_action_output(port = of.OFPP_FLOOD))
msg.buffer_id = event.ofp.buffer_id
msg.in_port = event.port
self.connection.send(msg)
2)This is print info:

There no flows on SWs.
3) SW's user can't communicate each other, but l2_learning or l2_paris work
smoothly.

Subject: Re: [pox-dev] how to use l2_multi ?
That commandline should work.
Can you post more info? For example, run with logging at DEBUG level and post
the log. Also... why do you think it isn't working? Why do you think POX
isn't handling it? In general, please see the last section of the FAQ in the
manual, and post as much information as you can.
Also, have you tried other forwarding components (e.g., l2_learning or
l2_pairs)?

Hi all,
Run " ./pox.py forwarding.l2_multi " on my machine, and OVS connected POX
correctly.
I found Packet_IN have send to POX, but POX l2_multi not handle it .
Does run " ./pox.py forwarding.l2_multi " is correct? or how to use l2_multi?
